The Committee on Earth Observation Satellites (CEOS) was established in 1984 in response to a recommendation from a Panel of Experts on Remote Sensing from Space and set up under the aegis of the G7 Economic Summit of Industrial Nations Working Group on Growth, Technology, and Employment. This Panel recognized the multidisciplinary nature of space-based Earth observations and the value of coordinating international Earth observation efforts to benefit society.

Accordingly, the original function of CEOS was to coordinate and harmonize Earth observations to make it easier for the user community to access and use data. CEOS initially focused on interoperability, common data formats, the inter-calibration of instruments, and common validation and inter-comparison of products. However, over time, the circumstances surrounding the collection and use of space-based Earth observations have changed.

This presentation provides an overview of CEOS and shows some examples of the numerous CEOS achievements, thanks to the scientific and technological cooperation of the major space agencies in the world, and the interoperability of their assets.

Ivan Petiteville graduated in 1984 from the École Polytechnique (France) where he studied Mathematics and Theoretical Physics. He also owns an engineering diploma in Informatics and Advanced Computer Science from the Ecole Nationale Supérieure des Techniques Avancées (France).

He joined ESA in 1988, first as Principal Ground Segment System Engineer for ERS-1 and then Project Manager of several Earth Observation satellite ground segments.

Since 2000, Ivan has occupied various functions in the Committee on Earth Observation Satellites (CEOS – https://ceos.org):

• Chair of the CEOS Working Group in Information Systems and Services,

• CEOS Executive Officer,

• Chair of the CEOS Working Group on Disasters between 2011 and 2015, he led the CEOS Delegation at the 3rd UN World Conference on Disaster Risk Reduction in Sendai (Japan).

In addition, Ivan has taken several roles in the Group on Earth Observations (GEO - https://earthobservations.org/) since its inception in 2005, e.g. co-Chair of the GEO Architecture and Data Committee between 2006 and 2012 and co-Chair of the GEO Programme Board 2018 - 2020.

P.S. Ivan was an inspired stage master’s student at the NRC Engine Lab.
